Cooking with a slow cooker

Typically every other week, we have a slow-cooked meal at home. Along with sous vide cooking, which I wrote about last month, slow cooking a form of low temperature cooking where the food isn’t heated as much, but cooked for longer.

We use our Instant Pot as a slow cooker. During my blogging hiatus, I wrote on Medium why a multi-cooker is a good slow cooker. The gist of it being that you can use its timer features both to delay the start, and reduce the cooking temperature at the end to keep the food warm. However, the Instant Pot’s sautĂ© mode is also helpful, if you need to pre-fry ingredients before starting the slow cooker timer. It’s not perfect, and there are some things that you need to bear in mind when using an Instant Pot as a slow cooker, as the temperature modes are not always comparable.

We used to have a dedicated slow cooker, but it was basic, and took up space that we needed for the more capable Instant Pot. The most basic models have one heat setting and turn on as soon as they’re plugged in, but many include multiple temperature settings and timers now.

Benefits of using a slow cooker

To me, there are several benefits of using a slow cooker over cooking meals using ‘traditional’ high heat methods.

The first of these is cost. Generally, it will cost less to run a slow cooker, even for several hours, than a hob or an oven for a shorter period. This is especially true for us, as we have solar panels – a slow cooker lets us do the majority of cooking during daylight hours with our free solar energy. In the winter, it’s dark when we get home after work and, even with a home battery, the amount of energy needed to run an oven means that we have to pay to use grid energy. I suspect that the cost of living crisis is one reason why slow cooking has become more popular in recent years.

Many slow cooker recipes simply require you to put the ingredients in the slow cooker, and leave it. They’re therefore quick to prepare, with no need to stir or keep an eye on a pan. You can put the ingredients in and turn the slow cooker on before leaving for work, and come home to a delicious meal that doesn’t require any work. If I’m working at home, I tend to put slow cooker meals on during my lunch break. Friends of mine who have issues with chronic fatigue find slow cooker recipes really beneficial, as it means they have something to eat at the end of the day which doesn’t require preparation, even when they’ve run out of spoons.

As with other low temperature cooking methods like sous vide, slow cooking is great for tenderising tougher cuts of meat like brisket. Coincidentally, these tend to be the cheaper cuts, and so you can save money this way too.

Not just soups and casseroles

There’s a perception that you can only use slow cookers for liquid-based meals like soups, stews, curries and casseroles. That’s not actually the case, and you can cook a wide variety of meals if you layer the ingredients correctly. In some cases, you essentially steam-cook ingredients that sit on top of others. Some recipes allow you to add rice, noodles or pasta shortly before the end, so that you can cook an entire meal in one pot.

That being said, one thing you are not going to get from using a slow cooker is anything crispy. That crispiness comes about thanks to the Maillard reaction, which usually requires cooking temperatures of at least 115°C. Even on their highest settings, slow cookers do not get as high as that. As such, some recipes call for ingredients like meat to be flash fried before or after slow cooking.

Slow cooker cookbooks

Last summer, I wrote about our go-to cookbooks, which included Nathan Anthony’s Bored of Lunch book (sponsored link). He has also written a follow-up – Bored of Lunch – Even Easier (sponsored link) which I’ve included in the photo above. We don’t use this as often as the first book, but there’s a nice recipe for Butter Chicken in there which uses yoghurt rather than cream. We also picked up his latest book, 6 Ingredient Slow Cooker (sponsored link), last weekend. It looks good but we’ve not attempted any of the recipes in there yet.

The first slow cooker book we bought was Slow Cooker Heaven by Lorna Brash (sponsored link) which is published by The National Trust. There are some good recipes in there, but they’re quite involved – some of them require a lot of preparation prior to turning the slow cooker on, or ask you to make your own spice mixes from scratch.

More recently we’ve picked up Poppy Cooks – The Actually Delicious Slow Cooker cookbook (sponsored link) by Poppy O’Toole. Poppy is apparently the ‘potato queen of Tiktok’, and used to be a professional chef before ending up out of work due to the Covid lockdown in 2020. Her recipes are generally also quite simple, and a little more authentic. We’ve cooked quite a few recipes from this book recently – Honey Garlic Chicken Thighs probably being my favourite.

For us, slow cooking tends to work best if I’m either working at home, or if Christine is working on a weekend. In the latter case, she can be held up and may not finish until 7pm, in which case it’s great coming home knowing that dinner can be ready and on the table within a few minutes, and with little effort.

Our go-to cookbooks

Cooking at home is one of my wife’s passions, although it’s something I enjoy too. Over the years, we’ve amassed a selection of cookbooks, but there are four that we use the most at present. So, partly as a way of sharing nice recipes, and partly as a cynical way of getting Amazon affiliate commission, here are our four go-to cookbooks.

All the links to Amazon below pay me a small amount of commission should you choose to buy these books from there. However, we often borrow cookbooks from our local libraries. I’ve also added links where some of these recipes are available online.

India Express by Rukmini Iyer

Of the four cookbooks mentioned today, India Express by Rukmini Iyer is our newest. We found it first in our local library, and then bought a copy as there were so many recipes that we wanted to try. All the recipes are vegan, vegetarian or pescatarian, and are generally quite quick – almost all can be done in an hour and many less.

Our favourite recipe so far is Spiced Roasted Paneer with Tomatoes and Peppers (available at this link). Paneer is an Indian soft cheese that you can usually get at larger supermarkets – our local Sainsbury’s stocks it in the chilled world food section. The recipe is basically a traybake – preheat the oven, put the ingredients in a roasting tin, and cook for 30 minutes. We’ve also enjoyed the South Indian-Style Black Pepper & Fennel Prawns recipe and had this a couple of times.

Bored of Lunch by Nathan Anthony

Nathan Anthony’s Bored of Lunch: The Healthy Slow Cooker Book, is apparently the biggest selling slow cooker cookbook in UK publishing history. I can see why – there’s some really good recipes, and the majority just require you to throw all the ingredients together and leave the slow cooker to do its thing. Other slow cooker cookbooks add on significant extra preparation, and undermine much of the ease and time saving that a slow cooker offers.

We typically have a slow cooker meal once a fortnight, using the slow cook mode on our Instant Pot. Almost all of the recipes come from this book, and the most recent we had was the Chicken and Peanut Curry, made from peanut butter and coconut milk. We also like the Thai Basil Beef and Gin-Infused Spiced Beef, and I was really impressed with the Garlic Parmesan Chicken with Potatoes which involves layering the ingredients to get a full meal in one pot. We also have the follow-up, Even Easier, but use the first book more.

Persiana Everyday by Sabrina Ghayour

We’re both big fans of Sabrina Ghayour’s Persiana cookbook, but we use the follow-up Persiana Everyday more often. I would recommend both if you like Middle Eastern cookery or food with a lot of flavour. We’ve recently tried the Sage Butter, Feta & Black Pepper Pasta, and our favourites are the Baked Halloumi and Za’atar, Paprika & Garlic Chicken.

There’s also some good side-dish recipes, especially for making flavoured rice.

Nigella Express by Nigella Lawson

Christine had this book when I met her, and though it was published 17 years ago, it still gets plenty of use. We have several of Nigella’s cookbooks, but Nigella Express is the one we use the most.

We recently had Mirin-Glazed Salmon for the first time, and Chicken Schnitzel with Bacon and White Wine is a favourite of ours. No Churn Pomegranate Ice Cream is a great base for lots of ice cream flavours that can be made without a dedicated ice cream maker.

Honourable mentions

We don’t own it, but we’ve cooked several good recipes from Donal Skehan’s Super Food in Minutes – we particularly like his Red Lentil Daal which we have with paratha. Most of the recipes in this book come with lots of vegetables.

If you have an Instant Pot, or another brand of pressure cooker, then Modern Pressure Cooking by Catherine Phipps is a worthwhile purchase.

Dishonourable mentions

My wife has gotten rid of several of her cookbooks recently, having not really used them. Jamie Oliver’s 15 and 30 Minute Meals both went – I’m sure you could cook the meals in 30 minutes with a full team of staff but they seemed to take us far longer. We also picked up the first two River CafĂ© cookbooks at a charity shop, and they’ll probably end up back there soon too. The Grains as Mains book seemed like a good idea, but we were underwhelmed – some are really basic recipes that just happen to have some extra wholegrains sprinkled on.
